一种新型的磁谐振式无线充电阵列发射机制

摘要

无线充电在桌面传输中,对水平传输范围提出了更高的要求.一维发射阵列可以高效拓展水平传输范围,但同时会引入死区问题.因此通过利用磁感应波(Magnetoinductive Wave)来建立理论模型,从而帮助理解和分析死区的原因,规律及现象.根据原因和规律,提出一种新的发射机制,应用到一维发射阵列中.实验结果显示,一维发射阵列上死区不再出现,原非死区效率提升10%.所以新型发射机制可有效避免死区并提升效率.%The wireless power in the desktop needs a large horizontal range to transfer power. 1-D transmitter array can extend the horizontal range with high efficiency,but it also brings a problem of dead zones. Thus,adopting the magnetoinductive wave to build the theory model,so the reasons,the rules and the phenomenon of dead zones can be analyzed and understood intuitively.Based on them,a new transmitter mechanism is put forward and used in the 1-D transmitter array. The experiments show that the dead zones don't appear in the 1-D transmitter array and the effi-ciency of the original non-dead zones are improved by 10%. So,the new transmitter mechanism can avoid the dead zones and improve the efficiency.
